/ Be it known vthat I, ACHILLES COLLE, a

eitizen of Belgium, residing at oylestown, I in the county of Bucks andState of Penn- Sylvania, have invented cert-ain new and useful.Improvements in Marine Vessels, 'of

r ywhich the following lis a specification.'-

y vfloat supportl so mounted as to be freely mov-l The :presentinvention relates to improve- `mentsinshipconstruction of .that type inthe body of the vessel is carried -by anlendless float support, and ithas for its object to` provide such a constructionn as will lserve toincrease the speed-with which the boat may be moved through, ormorestrictly speaking, upon .the surface of the water.

I .am aware of the factthat itha's been heretofore proposed to constructa ship answering broadly to the above idea but 'such propositions, have'embodied power instrumentalities for' driving' the endless iloatsuplport, .whereas in contra-distinction it 'is comprehended by myinvention te provide a able4 Vunder. the action of the resistanceoffered by the water incident to 'the propulsion of the boat by meansentirely independent of said. 'float device.

For a full understandingof the present A, invention, reference is to behad to the fol- 30 Fig. 5 is a verticalsection on'the.y linel 5 5 einig.i. y

Throughout the following detail description, and on the several figuresof the drawing, similar parts are referred to by llke referencecharacters.

Referring to the general embodiment of the -idea disclosedin Figs. 1 to3,`the vessel consists of a suitable form .of body embody-v ing a lowerdeck 1 and an upper deck 2 about .which is suitably mounted thelongitudinally extending float support 3. "It is preferred in thelargerShip constructlons that the space specificati@ of Letters raam.

between the upper and lower decks 1 and 2 will be suilicient toall'ord'cargo space and accommodate the power' mechanism which in thisinstance consists of the power plant .4

with driving shafts 5 extending to air propellers 6 mounted upon the topdeck Textending over and covering the upper portion of the endless'floatsupport 3 above referred to. lt to be understood that any kind ofpropulsion means may be employed and I.

therefore do'not wish to be'pconined to the "air propulsion mechanismherein disclosed.

:Where a marine engine of the internal combustion type is employed, afuel tank is suitably disposed at one end oiv the compartment betweendecks l and 2 as indicated at 8.,' As a matter of fact,the general ideavof this invention is applicable to aboat of small size in which nopropulsion means is employed other than that afforded by man-- ualmanipulation, as will be obvious to' any one skilled in the art to whichthe invention appertains.

The float support, as shown in Fig. 3 consists of a series of closedfloat membersor receptacles 9 containing a medium affording suitablebuoyancy and said elements vare connected together by the pivot rodconnections indicated at 10. 0n each ,end of the rod elements aremounted wheels -11 having suitable roller bearings to decrease frictionto the minimi m, said wheels being movable upon the d uble tracks or4ways12. This form of support is particularly useful in that it preventsdisplacement of the endless'member from its supporting way, as will beobvious. v

The endless member thus described-is entirely free tomove in alongitudinal direction upon its track way as the resistance of I9x5 thewater tends 'to shift the same when the boat is moved in eitherdirection of its travel. Thus lthe usual skin friction which is presentin' vessels of the conventional type is eliminated and substantially allthe v resistance which is present in this construction isthatwhicharises from'the movement ofthe weight upon the track way, obYiously aminimum amount due to; the frictionlessl bearing support vwhichit'provides. 105'V The boat is preferably provided with a rud- Y der 1 5at eachside -of the-'boat for suitably controlling its direction oftravel.

Passing now to the ymodified form of this deviceiwhich is shown in Figs.4 and5, the 110 endless support consistso s series of 50st elements in.itself consists of endless dootv constructionu Qlflius each floatelement 9' embodies a series ont smell iloetcompertments or elements 13connected together and mounted upon a track Way lst so that 'the endlessmember is free to move transversely.

of the boat., u

From this description it will appear that in this type of endlesssupport We lieve e general movability of the complete endless iioatmember longitudinally of the boat es well as e transverse movability ofeach of the float elements which form the constituent part of the mainfloat support. This type of construction is particularly adver' tsgeousin turning.;l movements of the vessel because any pressure of the Waterin e direction transversely of the Hoet support affects the individualfloat members and reduces resistance offered in such transversedirections.

It will be apparent that changes may be made in the'details ofconstruction of the elemental ports oit' the float device abovedescribed vvithout depertiuugn from the spirit of the `invention andWithin the scope of the t appended claims.
